So you're saying, Steve, that 25 1/2 and 52 1/2 for station 3 and 5 respectfully at the top longeron are not correct? I certainly hope this is not the case since my fuse was built to those dimensions. Will my angle of incidence be off after using the "corrected dimensions? Great idea though to use a full size rib during fuse construction.
